Gasoline fuels

We supply our owner-customers two gasoline grades differing mainly by their octane rating and ethanol concentration.

Renewable components are added to gasoline grades. The most widely used component is ethanol.

Octane rating is the most important factor
for choosing the right gasoline product

The most important factor for choosing the right gasoline product is the octane rating specified for the engine. If the instruction manual requires using fuel with higher octane rating than 95, the 98E5 grade petrol must be used. 

Gasoline grades are produced separately for summer and winter conditions. The volatility of winter grade, i.e., the steam pressure is higher than the summer grade.

Did you know?

The most popular gasoline grades in Finland are 95E10 and 98E5.

The first gasoline grade number (95 or 98) describes the product’s octane rating and the following number the maximum ethanol content (5 or 10%).

The octane rating describes the compression resistance of the gasoline and affects its ignition timing in the engine.

Gasoline 95E10

Gasoline 95E10 is suitable for most cars currently in use. The maximum ethanol concentration of this basic gasoline grade is 10 per cent by volume.

95E10 is suitable for nearly all car models manufactured in the 2000s. If you have doubts on whether the higher ethanol concentration is compatible with your vehicle or gasoline-powered machine, or if you own an older car, we recommend checking whether the 95E10 grade is suitable for the engine. 

You can check the compatibility of 95E10 gasoline with specific passenger car models here.

Gasoline 98E5

An alternative to the 95E10 gasoline is 98E5 which is suitable for all engines as the ethanol content does not exceed 5 per cent by volume. This alternative is also compatible with four-stroke and two-stroke engines requiring high-octane gasoline. In addition to these, 98E5 is a good choice for those gasoline engines which require octane ratings higher than 95 or are equipped with an engine control system that can make use of the advantages offered by a higher-octane rating.
